Normalization of non-standard words with finite state transducers for russian speech synthesis

Abstract

This paper describes finite state transducers employed for expansion of numbers, acronyms and graphic abbreviations into full-word numerals and phrases in the task of Russian speech synthesis. The developed finite state transducers cover cardinal and ordinal numbers, convert phone numbers, dates, codes, etc. The developed project is the first Russian open-source normalization system known to the author.
